PN ATI Capstone Pharmacology 1 Quiz

Correct Answer: C

Rationale: The correct answer is C: Oxybutynin. Oxybutynin is an anticholinergic used to treat overactive bladder, not a UTI. The nurse should verify this prescription because it may not be appropriate for a UTI. Choices A, B, and D are antibiotics commonly used in the treatment of UTIs. Ciprofloxacin, trimethoprim-sulfamethoxazole, and nitrofurantoin are more suitable choices for the treatment of a UTI compared to oxybutynin.

Correct Answer: B

Rationale: The correct answer is B: Limit alcohol consumption. When managing hypertension, it is crucial to reduce alcohol intake as it can raise blood pressure. High alcohol consumption can also interfere with the effectiveness of antihypertensive medications. Choices A, C, and D are incorrect. Increasing sodium intake (Choice A) is not recommended for hypertension as it can lead to fluid retention and elevated blood pressure. Eating a high-protein diet (Choice C) or following a high-fat diet (Choice D) are also not ideal for managing hypertension, as they can have negative impacts on cardiovascular health.

Correct Answer: B

Rationale: The correct answer is B: 'Suppression of airway mucus production.' Methylprednisolone, a corticosteroid, is known to suppress airway mucus production. While corticosteroids can enhance the responsiveness of beta2 receptors, they are not directly involved in the suppression of these receptors (Choice A). Corticosteroids can lead to adverse effects such as bone loss, rather than fortification of bones (Choice C). They can also increase the risk of infections like candidiasis but do not directly suppress it (Choice D). Therefore, the most expected pharmacological action of methylprednisolone therapy is the suppression of airway mucus production.

Correct Answer: B

Rationale: The correct answer is B: 'Drink at least 2 liters of water per day.' Clients taking allopurinol should be instructed to drink plenty of water to prevent kidney stones, a potential side effect of the medication. Option A is incorrect because allopurinol is usually taken without regard to meals. Option C is not directly related to the teaching about allopurinol, as it pertains more to dietary management of gout. Option D is also unrelated to allopurinol use for gout.

Correct Answer: D

Rationale: Corrected Rationale: Signs of dehydration include dry mucous membranes and decreased urination, among other symptoms. Bradycardia is not a typical sign of dehydration; instead, tachycardia (increased heart rate) is more commonly associated with dehydration. Therefore, option A is incorrect. While dry mucous membranes and decreased urination are indicative of dehydration, selecting only one of these symptoms would not provide a comprehensive assessment. Hence, option D, which includes both dry mucous membranes and decreased urination, is the correct choice.
